UPS Power System Repair

This entry was posted by on Wednesday, 1 February, 2017 at

PACE and other systems in the Rich 133 computer room experienced a brief power event on the afternoon of Monday, January 30th. This power event involved significant failure of one of the three uninterruptible power supply (UPS) systems that supply the Rich computer room with stable, filtered power. The UPS system switched over to bypass mode as designed and one of the main power feeder transfer switches also experienced a failure. Stable power continued to the PACE systems and all systems and network devices continued to operate without interruption.

Repair of the failed UPS is underway but parts may not be available for up to two weeks. During this time, the UPS power system will remain in bypass mode connecting many of the PACE systems to standard campus power. Our experience shows the campus power is usually clean enough to operate normally and so we are operating normally. Repair and re-testing of the UPS can take place without interruption of the existing power. We will announce this repair transition when we have additional information.

Should there be any significant campus power interruption during this interim time, we may lose power to some of the PACE systems. Rest assured the PACE staff will do our best to recover all systems affected by such an event. We will keep you informed via blog and announcement mailing lists of the repair progress.
